to the accompanying drawings, which form a part hereof.

My invention relates to the construction of brushes and has for its object to provide a coiled wire brush of great durability, and preferably of a composite character having its periphery made up in part of spirally twisted coiled wires and in part of bristle like material. The nature of my invention will be best understood as explained in con-' nection with the drawing in which I Figure 1 is a side View of my improved brush in what Iv believe to be its best form.

Fig. 3 a twisted coiled wire in full lines and the bristles in dotted lines. A is the handle of the brush to which are secured the wires B B, which are twisted together, as shown. Cis a spirally coiled .wire held between the wires B B, and twisted by them into the form of a spiral brush. Brushes formed in this way are well known, but are liable to breakage of the wire in use.

particularly at the-point where the wire 1s clamped between thewires B. B. They are also particularly useful as scrapers for the insides of tubes, but are not as elllcient in i what I may call theirsweeping action as are bristle brushes. In my new COIlStIilQtlOn I- provide a layer. or ribbon of bristles or bristle like material, which I twist between the wires B B together with the spirally twisted Specification of Letters Patent.

I have also found it desirable to form the ends E and F of my brush of bristles alone,

as shown in Fig. 1.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is;

A brush having a stem formed of twisted wires. in combination with, a*c 0iled wire twistedinto a spiral brush and held between the wires of the"stem, and'a layer ofbristle like material also twisted into a spiral form wires of the coiled wire and a layer of bristlelike ma terial twisted and held between the wires of the stem, the bristles pro ecting from the stem to approximately the same distance as the coiled wire so as to form a composite wire and bristle brudl. 3 A brush having a stem formed of twist ed wires in combination with a spirally coiled wire and a layer of bristle like mate MAX vnno k,
